Cannot open two files through file browser

[Tiago Sousa]

When listing files in the file browser (ctrl+o), if I select two files and then press open, nothing happens.

Under the hood, this happens (untill 'language*' it's only the window openning):

/usr/lib/python2.5/site-packages/TextFlow/ui/preferences.py:49: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
  self.widgets_tree = gtk.glade.XML(self.gladefile)
language triggers directory not found.
